サーバーへのアカウントの登録に成功しましたが、INVITE リクエストを開始したときに応答が返されません。
以下は、私が得た応答 (REGISTER 応答を含む) です。最終的に、発信 INVITE 要求が応答を返さないことがわかります。

ご覧のとおり、INVITE リクエストが送信された後に停止しました。
前もって感謝します、
アダム。
さらに詳しい情報:
user2932861 の提案を試してみましたが、うまくいきませんでした。パブリック IP アドレスを使用してみましたが、まだ INVITE 要求でスタックしています。また、SDP コンテンツを設定しました。以下は SDP コンテンツです。
ContentTypeHeader contentType = this.headerFactory.createContentTypeHeader("application", "sdp");
String sdpData = "v=0\n" +
"o=user1 392867480 292042336 IN IP4 *my IP*\n" +
"s=-\n" +
"c=IN IP4 *my IP*\n" +
"t=0 0\n" +
"m=audio 8000 RTP/AVP 0 8 101\n" +
"a=rtpmap:0 PCMU/8000\n" +
"a=rtpmap:8 PCMA/8000\n" +
"a=rtpmap:101 telephone-event/8000\n" +
"a=sendrecv";
byte[] contents = sdpData.getBytes();
request.setContent(contents, contentType);
注: IP アドレスは検閲されています。
前もって感謝します!
実際のところ、まったく応答が返されませんでした。しばらく沈黙した後 (何も返さない)、コンソールに「トランザクション タイムアウト」が表示されました。なぜこれが起こっているのですか?
